IRCT20220705055372N1 IRCT 2022-08-19 Mashhad University of Medical Sciences The effect of balance training with cognitive task Comparing the effect of dual task balance training with single task balance training in subjects with anterior cruciate ligament reconstruction: A randomized controlled trial 2022-08-23 anticipated 26 Complete https://irct.ir/trial/65183 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Supportive, Randomization description: Random block allocation method with volume 4 will be used. All possible 4 permutations will be listed in two groups. (Permutations 1 to 6 as follows) A is the intervention group and B is the control group. 1-AABB 2-ABAB 3-BAAB 4-BABA 5-BBAA 6-ABBA Then, from the random numbers table with random starting point, 6 will be selected between 1 and 6 by accident (either using software or randomaize.com site).For example, if the 6 random numbers obtained are 3 5 4 3 4 6, it will mean that the first four are similar to block 3, the second four are similar to block 5 and ... They'll be allocated, Blinding description: In this study, evaluators, analyzer were kept blind. N/A People or patients with anterior cruciate ligament reconstruction. Intervention 1: Intervention group: patients receive 60 minutes of treatment for 4 weeks and 3 sessions per week in a total of 12 sessions. In the intervention group, patients are initially treated with conventional physiotherapy for 30 minutes and then perform balance exercises that coincide with cognitive task for 30 minutes. Intervention 2: Control group: patients receive 60 minutes of treatment for 4 weeks and 3 sessions per week in a total of 12 sessions. In the control group, patients are initially treated with conventional physiotherapy for 30 minutes and then perform balance exercises separately for 30 minutes. Undecided - It is not yet known if there will be a plan to make this available Justification or reason for indecision in sharing IPD is there is no more information.

In the intervention group, patients are initially treated with conventional physiotherapy for 30 minutes and then perform balance exercises that coincide with cognitive task for 30 minutes. Control group: patients receive 60 minutes of treatment for 4 weeks and 3 sessions per week in a total of 12 sessions. In the control group, patients are initially treated with conventional physiotherapy for 30 minutes and then perform balance exercises separately for 30 minutes. Star Excursion Balance Test. Timepoint: This assessment is done before and after treatment. Method of measurement: This tool is used as a widely used dynamic test for clinical and research trials that evaluate a person's dynamic balance and this test requires strength, flexibility and depth perception. While standing on one leg (injured leg), the tester must move the other leg along eight directions and the person's displacement will be measured and will be calculated as the person's score. Single Leg Stance on Force Platform. Timepoint: This assessment is done before and after treatment. Method of measurement: The force plate is a tool that measures information about the state of the body and uses oscillation amplitude to evaluate this information. This amplitude is obtained from the minimum and maximum distance from the pressure center recorded by the device, and the lower the amplitude, the better the stability. Another parameter of the force plate is the sway speed, which is defined as the total displacement of the center of pressure on the total time the person has been on the device, and the lower the sway speed, the better the state stability of the individual. Tegner Activity Scale. Timepoint: This assessment is done before and after treatment. Method of measurement: This scale is used to record the activity level of both groups. The numerical amplitude of this scale is in the range of 0-10. The higher the score on this scale, the higher the activity level. Knee Injury and Osteoarthritis Outcome Score (KOOS). Timepoint: This assessment is done before and after treatment. Method of measurement: A questionnaire used to assess the outcome of knee injuries and knee joint function. This questionnaire includes 5 dimensions related to pain, symptoms related to illness, life activities, recreational sports activities and quality of life. The score of this questionnaire is between 0-100, which means the maximum disability score and the score of 100 means that the person has no disability.
